A lot of Linux executables have *.bin or *.sh extension. The *.bin extension
for Linux, bears no relation to files with the same extension on the Mac OS.
When you download a program for Linux, is usually in an archive format
with a double extension like *.tar.gz or *.tar.bz2. I believe these are
known as "archived tarball files" or something like that. These files
contain the necessary executables and documentation, including
instructions on how to install or compile the application.
Meanwhile, when you download a program to run on Mac OS X, which is
also based on Unix, sometimes it will have a *.dmg.gz double extension
or a *.dmg.bin double extension. These files are archived, in a similar
way to those archived for Linux, and when they're unpacked, they're
referred to as "self mounting disk images", as they appear on the
desktop as though they are actually disks, but they're really
just disk images, containing all of the relevant executable,
files, and all of the necessary documentation . . .
